Density is equal to the ratio of mass to the volume.
The mathematical expression is given as:
[tex]Density = \frac{mass}{volume}[/tex]
Density of silver metal bar=[tex]10.5 g/cm^{3}[/tex]
Convert [tex]g/cm^{3}[/tex] into g/L
[tex]1 cm^{3}[/tex] = 0.001 L
Thus, density = [tex]\frac{10.5}{10^{-3}} g/L[/tex]
= [tex]10.5\times 10^{3}g/L[/tex]
Volume = 0.5 L
Put the values,
[tex]10.5\times 10^{3}g/L= \frac{mass}{0.5 L}[/tex]
[tex]m= 10.5\times 10^{3}g/L\times 0.5 L[/tex]
=[tex]5.25 \times 10^{3}g[/tex]
Now, convert gram into kg
1 g = 0.001 kg
Therefore, mass in kg= [tex]\frac{5.25 \times 10^{3}}{10^{-3}}[/tex]
= 5.25 kg
Thus, mass of silver metal bar in kg=5.25 kg
The study of chemicals is called chemistry. Anything which occupies mass and volume is called matter.
The correct answer is 5.25kg.
What is density?
- The density of a substance is its mass per unit volume.
The formula used to solve the question is:-
[tex]D =\frac{M}{V}[/tex]
Data is given as follows;-
- The volume is 0.5L
- Mass is 0.001.
Place all the values to the equation and these are:-
[tex]\frac{5.25*10^3}{0.001}[/tex]
Hence, the correct answer is 5.25.
